As per this Documentation,我正在尝试使用以下命令从pod中访问Kuberenetes API
curl --cacert ca.crt -H "Authorization: Bearer $(<token)" https://kubernetes/apis/extensions/v1beta1/namespaces/default/deployments/ballerina-prime/scale
遵循以下模板
curl --cacert ca.crt -H "Authorization: Bearer $(<token)" https://kubernetes/apis/extensions/v1beta1/namespaces/{namespace}/deployments/{name}/scale
它引发以下错误
{
"kind": "Status",
"apiVersion": "v1",
"metadata": {
},
"status": "Failure",
"message": "deployments.extensions \"ballerina-prime\" is forbidden: User \"system:serviceaccount:default:default\" cannot get resource \"deployments/scale\" in API group \"extensions\" in the namespace \"default\"",
"reason": "Forbidden",
"details": {
"name": "ballerina-prime",
"group": "extensions",
"kind": "deployments"
},
"code": 403
}
有人可以指出我在哪里出错,或者提出其他可以访问Kubernetes API的方法吗?
更新01
我根据建议的文档创建了一个角色。以下是我使用的清单。
apiVersion: rbac.authorization.k8s.io/v1
kind: Role
metadata:
namespace: default
name: deployments-and-deployements-scale
rules:
- apiGroups: [""]
resources: ["deployments", "deployments/scale"]
verbs: ["get", "list"]
我使用此命令将其应用。 kubectl apply -f deployments-and-deployements-scale.yaml
。仍然无法访问所需的端点。我在哪里犯错?

首先,您已正确连接到kubernetes API!
但是您使用的默认服务帐户(“用户”)没有执行所需操作所需的特权。 (在名称空间“默认”中读取部署“芭蕾舞女演员-prima”)
您需要执行的操作:使用其他服务帐户或授予默认服务帐户所需的权限。
您可以在文档中找到详细信息:https://kubernetes.io/docs/reference/access-authn-authz/rbac/

正如@Thomas在他的回答下方的评论中所述,您需要通过Role资源将特定的account分配给目标服务RoleBinding以便修复authorization问题。
参考您的清单:
apiVersion: rbac.authorization.k8s.io/v1
kind: Role
metadata:
namespace: default
name: deployments-and-deployements-scale
rules:
- apiGroups: ["extensions", "apps"]
resources: ["deployments", "deployments/scale"]
verbs: ["get", "list"]
---
kind: RoleBinding
apiVersion: rbac.authorization.k8s.io/v1
metadata:
name: deployments-and-deployements-scale-rb
subjects:
- kind: ServiceAccount
name: default
namespace: default
roleRef:
kind: Role
name: deployments-and-deployements-scale
apiGroup: ""
您可以考虑在角色定义中显式设置apiGroups:
,以匹配特定的API组,或者广泛搜索["*"]
,以查找所有API版本。
